Biblical account

Layer: Biblical text

Daniel continued until the first year of King Cyrus.

Historical overview

Layer: Historical reconstruction · Period: Cyrus's first Babylonian year (538/537 BC)

Babylonian documents count Cyrus's years from the fall of Babylon with an accession year; year 1 began 1 Nisan = 24 Mar 538 (Parker & Dubberstein). Daniel 10:1 dates a later vision to Cyrus's third year, so 1:21 is commonly read as marking the end of the Babylonian era of his service rather than his death.[1]

Kingdoms: Achaemenid Persian Empire

Date and chronology derivation

Ranges are computed by the project's deterministic chronology engine from the biblical statements and each model's reign anchors. They are reconstructions, not independent dates.

How this range was derived

Earliest bound

  1. “Daniel continued even to the first year of King Cyrus” — Daniel continues until the first year of King Cyrus (Dan 1:21) in regnal year reign of Cyrus II (the Great) (year 1) [reckoned accession, nisan new year] (Daniel 1:21)[1]Assumption: Counted in Babylonian years (accession year 539/538 not counted): year 1 = 24 Mar 538 – 12 Mar 537. Counting the accession year as year 1 would move the window about five months earlier (Oct 539 – Mar 538).
